As shown in fig. 6 and 7, the limiting mounting plate 240 needs to provide a corresponding number of limiting holes 241 at corresponding positions according to the number and positions of the supporting bump portions 210 mounted on the panel 100; the limiting installation plate 240 may be a fork-shaped structure plate formed integrally, or may be an annular structure, and in this embodiment, if the integrally formed fork-shaped structure is adopted, the limiting installation plate 240 is complicated in the production process or the waste of trimming scraps is too much, thereby affecting the production cost; in this embodiment, the limiting mounting plate 240 is formed by splicing a plurality of strip-shaped plates, a clamping groove 242 and a clamping protrusion 243 are arranged on each strip-shaped plate, and the strip-shaped plates can be clamped and positioned on a horizontal plane, and can be fixedly mounted on the bottom surface of the panel 100 by an adhesive or screws.

EXAMPLE III

A temperature detecting method applied to the induction cooker, comprising the following steps:

and setting control threshold parameters and early warning settings according to the cooking operation of the induction cooker.

And acquiring the difference range of the appointed temperature parameters of the temperature probe 230 in the appointed electromagnetic oven temperature detection structure.

The controller compares the difference range of the specified temperature parameters with the threshold parameters for analysis, and controls the induction cooker to normally perform cooking operation when the difference of the specified temperature parameters does not exceed the threshold parameters; and when the designated temperature parameter exceeds the threshold parameter, the controller sends out alarm information or stops the cooking operation of the induction cooker according to early warning setting according to an analysis result.

Specifically, the controller is provided with a control program, and the threshold parameters can be automatically set according to cooking modes of the induction cooker, for example, cooking modes of cooking dishes and cooking soup are different, and corresponding threshold parameters are also set differently; in the cooking process, the controller can carry out corresponding alarm information sending operation or stop the cooking operation of the induction cooker according to the difference between the designated temperature parameters, namely threshold parameter comparison and the control operation corresponding to the threshold parameters. Wherein, the designated temperature probe 230 refers to the temperature probe 230 contacting with the pot, and the temperature probe 230 can be manually input by the user according to the placing position of the pot during cooking, and can also be automatically screened according to the temperature parameters of each temperature probe 230 at the initial stage of cooking.

In this embodiment, in the electromagnetism stove when electromagnetism stove temperature detect structure is three or three more, generally three just can realize the temperature detection to the pan bottom surface, and when the pan was placed in top panel 100 top, the pan can guarantee at least with three electromagnetism stove temperature detect structure contact, when the electromagnetism stove during operation, according to the principle of three point support, specifically can divide into following several kinds of circumstances:

when the cooker is normally operated, the temperature of the induction cooker temperature detection structure is basically consistent, the tolerance can accept about 5 degrees centigrade (the temperature tolerance can be set according to the actual cooking condition), and the controller takes three to serve as the temperature value of the actual cooker for the average temperature of the induction cooker temperature detection structure. The temperature detection structure of the electromagnetic oven does not directly contact the pan bottom (the distance from the pan bottom can be adjusted according to the shape of the pan required by the equipment, and is preferably 1-5 mm), and the temperature detection method does not allow the temperature of the temperature detection structure to be higher than a threshold parameter. Once the temperature is exceeded, the dry burning can be judged, and the deformation of the cookware is possible.

When the dry-cooking pot deforms, the following possibilities occur: firstly, the burning or deformation protrusion appears at a certain temperature detection structure position, the temperature at the position is much higher than that at other points, and the system can directly judge within a few seconds. And secondly, pan burning deformation occurs between the two induction cooker temperature detection structures, the temperatures of the two induction cooker temperature detection structures are much higher than those of the induction cooker temperature detection structures without dry burning, and the controller can directly judge that abnormality occurs according to the temperature contrast of the three induction cooker temperature detection structures. Thirdly, when three electromagnetic oven temperature detection structures are simultaneously burnt or deformed, the temperatures of the three electromagnetic oven temperature detection structures can be continuously increased. And finally, the threshold parameter set by the cooking mode is exceeded, and the controller can judge that the induction cooker is abnormal in dry burning.

Because electromagnetism stove temperature-detecting structure can make the pan only with support bump portion 210 contact, the pan is in unsettled state, and the pan can not contact with panel 100, and the temperature of pan can not transmit for panel 100, can reduce energy loss about 80% for traditional electromagnetism stove, and the culinary art efficiency is higher.

The induction cooker greatly increases the induction cooker temperature detection structure, so that the probability of contact between the panel and the cookware is reduced under various cooking conditions, the temperature detection method is more sensitive to temperature detection of the cookware, and the induction cooker can be convenient to switch temperature detection control modes intelligently according to different cooking modes; meanwhile, when an abnormal condition is met, accurate judgment can be made at a higher speed with higher probability, and the safety performance can be greatly improved.

Because the cooker does not contact the panel 100 and does not depend on the panel 100 as a bearing object, the heat received by the furnace body part of the induction cooker is greatly reduced, the panel 100 does not adopt microcrystalline glass, and cheaper borosilicate glass or common toughened glass can be used. The panel 100 can also be directly encapsulated and protected by other modes, such as encapsulation and curing, and the production cost is lower.
